[HOWTO] Remove Ads from apk - Defy Themes and Apps

Hi there, here's a little tweak that I've just figured out and that hopefully some of you might enjoy...
But first off, a disclaimer:
Ads or (upgrade) nag banners 'sometimes' have a justifiable reason of being. Devs might use them to get some extra (very small un fact; most finally give this up in the end) revenue from them. That, in turn, that might allow or encourage them to continue pulishing more free apps for you to enjoy. So use your best judgement here and use these tweaks with discernment...​
Message to moderators: if this goes against xda policy in any way, please let me know and I'll remove all this from here.
OK, now that this is set clear, here's what that is all about:
I'm sure that most of you guys have seen ads (or upgrade) banners in free apps and being an xda member, you probably know a few tricks to get rid of some of them. I mean ads like the ones apps or games that do not really need internet connections can easilly be blocked by using ip-tables rules/firewall/anti-ads apks to completly block their internet (like with Droidwall for example). But what about ads on the apps that DO need internet connection and than cannot be completely blocked? What about the empty screen space left for banners on some others with blocked internet access?
Well, through my readings, I've found that some suggest to hack the apks and to simply decompile them, go in \decompiled_apk\smali\com\google\ folder and delete the "ads" folder altogether. Well, from my experience, this doesn't work very well. In many cases, the modded app will not install and in some other cases, the trick might work for a while and then the ads would eventually come back. That last case just happened to me: a while ago, I've tweaked the DI Radio app like so and things seemed just fine. And today, bam!!: ads banners again. God knows how/why they came back with that "ads" folder deleted, but they did!!
So with a little thinkering and code browsing, I've figured out a very simple way to get this done - here's how:
What you need:
- An apk decompiling/compiling/signing tool(s) of your choice;
- the excellent text editor notepad++ - get it from here
Notes:
- PLEASE, do not fill this thread with questions like: how do I decompile/sign apks? - it's not the place here - thanks!
- And please do not full-quote this long post either
- If you rewrite/repost this somewhere else, please play it fair and give credits/link to this thread.
HOWTO:
1. Pull and decompile your apk;
2. Go in \res\layout folder and select all the xmls files, right-click of the highlighted file and press "open" and they should all open with Notepad++ [just click OK if you get the "confirm 'Open' Action"];
3. Select Search/Find... and enter: "@id/ad" [no quotes ""] and press "Find ALL in All opened Documents" on the search popup dialog box;
4. Now look at the search results and there might be 2 possible (maybe more.. I've tried this on only 2 apks so far...) result types:
--> As a first illustration of this: for the DI radio apk I've mentioned above [I use an older version and not the latest that requires login every time...], you get an xml called "playing.xml" with this at line 6:
Code:
<FrameLayout android:layout_gravity="center" android:id="[COLOR="Red"]@id/ad[/COLOR]_frame" android:layout_width="[COLOR="Red"]320.0dip[/COLOR]" android:layout_height="[COLOR="red"]50.0dip[/COLOR]">
On that line, we can see some size attributes for that banner; just resize them to 0!!;
So all there is to do is to edit it like so:
Code:
<FrameLayout android:layout_gravity="center" android:id="@id/ad_frame" android:layout_width="[COLOR="red"]0.0dip[/COLOR]" android:layout_height="[COLOR="red"]0.0dip[/COLOR]">
-->> Second case: for some other apks (like for an older version of a very famous file explorer..), you might get multiple results (many xmls - 6 or 7 of them) all looking like this:
Code:
<com.google.ads.GoogleAdView android:layout_gravity="center" android:id="[COLOR="red"]@id/ad[/COLOR]view" android:layout_width="wrap_content" android:layout_height="wrap_content" />
So no banner sizes in this case but all there is to do is to delete all those lines completely and then save all the respective xmls. Then,
5. Recompile and sign the apk;
6. Backup [for restoring its data later..] and then uninstall your original apk from your phone (if still there)
7. Install your modded one and enjoy your app without any ads, blank spot or nag screen.
Final notes:
- Now, this doesn't stop the app to get the ads from the internet, but it does give you a simple way to hide them and this also make accidental clicks on them a story of the past...
- This is pure dirty hacking and not a general procedure; there might be different ways to implement ads in apps and ways to hide them; so please try at your own risk and feel free to share your results/tricks with us.
- Thanks to oSandmaNo for reminding me this one important drawback: when you tweak apps like so, you will get an error message when trying to update them on the Playstore. You will have to uninstall them before being able to update. so this mean that make a backup with Titanium Backup (or others) first in order to later restore the app's DATA ONLY. Obviously, the remove ads tweak will then be gone after the update, but since you've done it once, it should be fairly easy to do it once more..
- Read post #3 for a few additional tips.

Thanks buddy,
Well after a little more experimenting on this yesterday
[ ...nice way to spend time our last day on Earth... Oh wait! we're still alive; the doomsday that never came...], I realize(like I suspected) that there are many different ads implementation/removal methods and will have to had a few extra tips and tricks here.
I even still have an app that I can't figure out where the ad banner is.
But, if I may just add, the whole point here was to:
1- tell people that notepad++ is excellent tool for multi-open and multiple-files search tool - perfect for xmls...
and 2- make people realize that if ads are displayed on the screen, it is more than likely that there is/are entries about it somewhere in /res/layout/ that can be hacked...
Ok, from phone it's not convenient but here's one or two extra tips:
- search for "<com." and look for results related to google AdView or doubleclick - those can all be voided;
- if you find a line that you know/suspect is a banner, do not completely delete it and just use "<!--" (start - w/o ") and "-->" (end) to void that line;
- if a banner line entry is within a RelativeLayout, it might be preferable to add/change its size to zero with android:layout_width="0.0dip" (same with height) rather than void it;
- if you do the above (0 height/width), and the line has a: android:scaleType=fitXY" entry, delete it from the line. Other wise it might just bypass your change to 0 by 0 size...
- so search for "fitXY" is alao another thing to search for in the goose chase... so is "advert", "banner", "pub", ....
Ok, that's it for now...lack of coffee in the morning makes for messy posts...

So the difference between the results of this procedure and an adblock such as AdAway is? I'm just curious.

they will only block the ads but they keep a blank frame in the display and this will get rid of the whole frame

Yep, that's the idea!
Why can't I ever come up with those 1-liner answers...?!? :silly:
Baahh! since I've already written an answer in a notepad, I'll paste it here in anyway:
Similarly to anti-virus solution and their virus defintion lists, AdAway is an app that blocks ads through the use of hosts files. It basically downloads and keep updated a list of known ads (and rogue) sites and just blocks any internet connection to them using a local redirection. I've already posted something on all this here.
Btw, I personally do not see the point of using such a specific app just for this as there tons of such lists freely available on the net and I don't think it is that important to update it so frequently... I just update the list once every 3-4 months or so and everything has been fine for me so far...
On the other hand, the object of this thread is to deal with apks' layouts and that means to aim at removing any wasted space that the ads might use OR leave empty if you do block them out. Just look at the 4th screenshot on the OP; it might not be clearly visible because I put some text over it, but you see that black rectangle at the bottom? Well that is what I called an app banner. It's black because I used Droidwall to block internet access to that file explorer, but I believe that it would be the exact same if I would only use either AdAway or just my hosts file. It's the layout design of the apk that still uses that space even though it didn't get any ads from the internet...With my tricks, I (at least the goal is to) regain that important screen real estate no matter what; even without any ad blocking solution... And btw, none of those are perfect either; there will always be one new ad site not listed/included yet...
Like I wrote more than once above, not all apps are coded the same and some other apks do not display anything when they do not get any ads from the net. So these tweaks would not be needed for those.
I feel that what I wrote is a bit confusing, but I hope you get my idea anyway.
Added two more SS as example...
[that freakin app had ads entry in a good dozen different xmls but easy doubleclick ones :victory: ]

Adding
android:visibility="gone"
To any layout block (within < and /> ) having the word "ad" in it should work as well
And right on about notepad++ being great for xmls and I use it along with VTS10 which also previews referenced drawables, strings and public.xml entries in the xml apart from having a complete fuss free environment for reverse engineering apps
Thanx for sharing!

Thanks I wondered about that; I will try it out on the next app I tweak for this..

You mean searching for the word "ad" or adding that within the layout? Because searding for "ad" when an app 100+ xmls you will get A LOT of results with "android: paddingLeft=...(/right)"...

Thanks, I'll surely have a look at that VTS10 but when I tried to search for it I got just about every results possible (dry vaccum pumps, metal wires, remote house domotic system, etc...) except something related to Android

Can you update the app after modifying? No package signed incorrectly error?

I didn't mean it literally, just something to identify layouts containing adverts (lame, I know ). There'd be better ways of searching for it (like the id search you mentioned)

Oh! good that you mention this - I thought about it earlier today then I forgot about it...
You are right: you'll get that error and have to uninstall before beeing able to update.
This makes sense and even if you could, the update would replace the old version and remove your changes anyway.
So yes, this is an important drawback and I'll update the OP tomorrow.
I often tend to keep old versions unless new ones bring important fixes or options...why update what is not broken? hehe!
But at least, once you've found how the tweak is done for a specific app, it should be quite easy to do it again...
And really, I don't know about you, but I do not use that many such apps that show ads or blank space... Most don't if they do not absolutely require internet connection and if you use Droidwall and/or a hosts file.
But again, good point and thanks.

Maybe, but that has nothing to do with xda philosophy where the forum is there to make people learn and try mods on there own.
Beside, in my mind, this is pretty much warez talk and that is against xda rules...
So I won't thank you for the suggestion

thanks

cool!
thanking you twice today, mate!

Madvertise Ads !!!
Awsome tut dude! I've been on it already but now I've encounter some kind of new ad engine called Madvertise!
Can't seem to get rid of it! Do you or anybody aorund know how?
I seemed to have figured out some of its files...
\res\layout\ad_madvertise.xml
\res\values\attrs.xml
\assets\adview.html
\assets\adview.js
Messing around modifying/removing these files makes the APK file unusable!

---

Ty very much. I had problems with one app for coding. The ad covred the main sting while I was writing and I really could't see anything. But with ur help I can carry on with my work
P.S.: Does the ad eat traffic even when I can't see it? And I'm enclosing that app. Probably, some1 needs it.

---

thanks OP for great method
Thanks OP for this great method, i was having problems first when compiling but when i downloaded the latest apktool and aapt especially the decompiling was done with any problem. I removed ads from two apps as a piece of cake.
